Check tyre pressures and try a wheel alignment first.
I also had a front wheel drive car that had a similar problem and
i had to replace the front tyres.
I have had that problem with my 95 Legacy and after having it aligned for $150+
it pulled to the side just the same. New tires (rather inexpensive Hankooks)
fixed it.
My current Legacy (98 GT Wagon) slightly pulls to the right side again - after
replacing the worn Potenza RE 910 set with new Kumho HP4 716,
Here's the diagnostic method as on the tirerack site:

Step 1
Action to be Taken
Rotate the two front tires from side-to-side.
Results
1.
If the vehicle pulls in the opposite direction, the defective tire is one of the
front tires. (GO TO STEP 2)
2.
If the vehicle pulls in the same direction the problem is either with one of the
rear tires or is not a tire-related problem. (GO TO STEP 3)
Step 2
Action to be Taken
Rotate the front tire on the side of the car that is in the direction of the
pull, to the rear of the car.
Results
1.
If the pull no longer exists or diminishes greatly, the tire that was moved to
the rear of the car is the defective tire.
2.
If the pulling does not change, the defective tire is isolated to the front tire
that was not moved in Step 2.
Step 3
Action to be Taken
Rotate the two rear tires from side to side.
Results
1.
If the vehicle pulls in the opposite direction, the defective tire is one of the
rear tires. (GO TO STEP 4)
2.
If the pulling tire does not change, the problem is not tire related. The car
should be checked for possible misalignment or suspension wear.
Step 4
Action to be Taken
Rotate the rear tire on the side of the car that is in the direction of the pull
to the front of the car.
Results
1.
If the vehicle pull becomes more severe, the defective tire is isolated to the
tire that was rotated to the front of the car.
2.
If the pulling does not change, the defective tire is isolated to the rear tire
that was not rotated.
